A deviated septum is mainly caused by injury, congenital defects, or natural aging that shifts the nasal cartilage and bone off-center.
Understanding the Anatomy Behind a Deviated Septum
The nasal septum is the thin wall of bone and cartilage that divides the two nostrils. Ideally, this partition sits squarely in the middle of the nose, allowing equal airflow through both nostrils. However, when this wall is displaced to one side, it’s called a deviated septum. This deviation can range from mild to severe, impacting breathing and sometimes causing other complications.
The structure of the septum consists of both bone and cartilage. The front portion is mostly cartilage, which is more flexible, while the back part is bony and rigid. Because of this combination, several factors can influence its alignment over time or abruptly.
What Can Cause a Deviated Septum? The Primary Factors
There are three main categories that explain why a septum might deviate: trauma (injuries), congenital conditions (present at birth), and degenerative changes over time.
Trauma and Injuries
Injuries to the nose are by far the most common cause of a deviated septum. A sharp blow or impact to the face—like during sports accidents, car collisions, falls, or physical fights—can shift or even break the septal cartilage or bone. Sometimes these injuries happen during childhood but only become noticeable later in life as symptoms worsen.
Even seemingly minor trauma can cause subtle shifts. For example, bumping your nose against a hard surface repeatedly or forcefully can lead to gradual displacement. In some cases, nasal fractures accompany septal deviation.
Congenital Causes
Not all deviated septums arise from injury. Some people are born with their nasal septum already off-center due to developmental differences in utero. This means that during fetal growth, the bones and cartilage didn’t form symmetrically.
Genetics also play a role here; if family members have nasal structural abnormalities, there’s an increased chance you might too. These congenital deviations often remain unnoticed unless they cause breathing problems or chronic sinus issues.
Aging and Natural Changes
Believe it or not, aging can contribute to a deviated septum as well. Over time, cartilage tends to weaken and lose its firmness. This loss of support might allow parts of the septum to sag or shift slightly.
Additionally, repetitive minor injuries accumulated through daily activities—like rubbing your nose frequently or even sleeping positions—can exacerbate pre-existing deviations gradually.
Other Contributing Factors That Affect Septal Alignment
While trauma and congenital issues dominate as causes for deviation, some other factors may indirectly influence or worsen the condition.
- Inflammation and Infection: Chronic sinus infections can cause swelling inside the nose that might push against the septum.
- Nasal Tumors or Growths: Though rare, polyps or benign tumors inside nasal passages can distort normal structures.
- Improper Healing After Surgery: Surgeries involving the nose (like rhinoplasty) may accidentally alter septal positioning if healing doesn’t proceed smoothly.
The Impact of a Deviated Septum on Health
A deviated septum isn’t just an anatomical curiosity—it often leads to real health issues that affect daily life.
Breathing Difficulties
The most obvious problem is obstructed airflow on one side of the nose. This obstruction forces you to breathe through your mouth more frequently, which can dry out your throat and increase susceptibility to infections.
People with severe deviations may experience chronic nasal congestion that doesn’t improve with typical treatments like decongestants or antihistamines.
Sleep Disruptions
Poor airflow through one nostril can contribute to snoring and even sleep apnea—a condition where breathing repeatedly stops during sleep. Lack of restful sleep impacts energy levels, mood, and overall health.
Sinus Infections and Headaches
Blocked nasal passages create an environment where mucus cannot drain properly from sinuses. This stagnation leads to frequent sinus infections marked by pain and pressure around eyes and forehead.
Chronic headaches related to sinus inflammation are another complaint among those with deviated septums.
Treatments Based on Causes: What Can Cause a Deviated Septum? And How Do You Fix It?
Treatment depends largely on how severe symptoms are and what caused the deviation in the first place.
Non-Surgical Approaches
For mild cases where symptoms are manageable:
- Nasal Sprays: Steroid sprays reduce inflammation inside nasal passages.
- Decongestants: These temporarily shrink swollen tissues but shouldn’t be used long-term.
- Allergy Management: Controlling allergies reduces swelling that worsens obstruction.
- Nasal Strips: External strips applied at night help open nostrils slightly for better airflow.
These methods don’t correct structural problems but ease discomfort temporarily.
Surgical Correction: Septoplasty
When symptoms severely impact quality of life—such as persistent breathing difficulty or recurrent infections—septoplasty surgery becomes necessary. During this procedure:
- The surgeon repositions or removes parts of bent cartilage/bone.
- The goal is restoring straight alignment without affecting external appearance.
- This operation usually takes less than an hour under local or general anesthesia.
- Recovery involves some swelling but typically improves breathing dramatically within weeks.
In some cases where cosmetic appearance also needs adjustment (e.g., crooked nose), rhinoplasty may be combined with septoplasty.

| Cause Category | Description | Typical Onset Age |
|---|---|---|
| Trauma/Injury | Nasal fractures due to accidents, sports injuries, falls causing displacement. | Any age; most common in teens & adults. |
| Congenital/Genetic | Bent septum present at birth due to developmental anomalies in utero. | Birth/early childhood. |
| Aging/Degeneration | Nasal cartilage weakens over time leading to gradual shifting. | Middle age & older adults. |
The Importance of Early Recognition: Why Knowing What Can Cause a Deviated Septum? Matters
Ignoring symptoms from a deviated septum can lead to worsening problems down the line. Early recognition allows for timely intervention before complications like chronic sinusitis develop.
If you notice persistent nasal blockage on one side, frequent nosebleeds without apparent cause, recurring headaches around your sinuses, or loud snoring paired with daytime fatigue—it’s worth consulting an ENT specialist for evaluation.
A simple physical exam combined with imaging tests such as CT scans helps pinpoint exactly what’s going on inside your nose. Understanding what caused your deviated septum guides appropriate treatment decisions tailored just for you.

Frequently Asked Questions
What Can Cause a Deviated Septum from Trauma?
Trauma is the most common cause of a deviated septum. Injuries such as sports accidents, falls, or car collisions can shift or break the nasal cartilage and bone, leading to deviation. Even minor or repeated bumps to the nose can gradually displace the septum over time.
Can Congenital Factors Cause a Deviated Septum?
Yes, some people are born with a deviated septum due to developmental differences during fetal growth. These congenital causes result from asymmetrical formation of nasal bones and cartilage and may be influenced by genetics. Often, these deviations go unnoticed unless breathing issues arise.
How Does Aging Contribute to a Deviated Septum?
Aging can cause a deviated septum as cartilage weakens and loses firmness over time. This natural degeneration may allow parts of the septum to sag or shift slightly. Repetitive minor injuries accumulated during daily activities can also contribute to changes in alignment with age.
What Role Do Nasal Fractures Play in Causing a Deviated Septum?
Nasal fractures often accompany septal deviation by displacing the bone and cartilage structure inside the nose. Such breaks typically result from blunt trauma and can lead to both immediate and long-term breathing difficulties if not properly treated.
Are Repetitive Minor Injuries a Cause of Deviated Septum?
Repeated minor trauma, like frequently bumping or rubbing the nose, can gradually cause shifts in the septum’s position. Although less dramatic than major injuries, these small impacts accumulate over time and may lead to noticeable deviation.
Conclusion – What Can Cause a Deviated Septum?
What can cause a deviated septum? The answer lies mainly in three areas: trauma from injuries; congenital defects present at birth; and natural aging processes weakening nasal structures over time. Each factor shifts the delicate balance inside your nose differently but results in similar challenges like blocked airflow and discomfort.
Recognizing these causes helps identify when treatment is necessary—whether through simple remedies for mild cases or surgical correction for severe deviations. Knowing what causes this condition empowers you to take action early on before symptoms escalate into chronic issues affecting sleep quality and overall well-being.
By staying informed about these causes and their effects on nasal health, you’re better equipped to breathe easier every day!
